In accordance with the present invention, a toilet device is illustrated -as being installed -in a bombshelter which is preferably an underground structure. The toilet device is mounted on yone of the walls partially defining the bombshelter and is connected to a pipe extending through said one wall. The end of the pipe remote from the toilet device -is in communication with a waste receiving tank or the like. The toilet device is provided with a pivotably mounted cover having a reciprocably mounted plunger tube disposed therein. The inner surface Vof the bowl may be cleaned by means of reciprocation of the plunger tube and the introduction of liquids into the bowl by means of the plunger tube which is hollow. Means are provided to sealingly secure the cover to the bowl and to selectively seal the passage through the plunger tube.

It is an object of the present invention to provide a novel toilet device.

It is another object of the present invention to provide `a. novel toilet device particularly adapted for use in bombshelters or the like.

It is another object of the present invention to provide a toilet device which is in communication with a waste disposal tank and does not have a supply of water or other ushing liquid connected thereto.

It is another object of the present invention to provide a toilet device with a means for causing waste material to be removed therefrom yand conveyed to a waste disposal tank without the use of a water supply connected to said toilet device.

Other Iobjects will appear hereinafter.

For the purpose of illustrating the invention there is shown in the drawing a form which is presently preferred; it being understood, however, that this invention is not limited to the precise .arrangements and instrumentalities shown.

FIGURE 1 is a partial perspective view of an underground bombshelter with the toilet device supported by one yof the walls of the bombshelter.

FIGURE 2 is a sectional view of the toilet device illustrated in FIGURE l.

Referring to the drawing in detail, wherein like numerals indicate like elements, there 4is shown in FIGURE l a bombshelter designated generally as 10.

The bombshelter includes a iloor 12, a wall 14 whicl is upright with respect to the oor 12, a wall 16 and a wall 20. The walls 14, 16 and 20 partially define the enclosure of the bombshelter. A wall 18 is disposed parallel to the wal-ls 16 and 2G and defines a passageway therebetween through which persons may gain -access to the doorway 22.

The passageway between the walls "18 and 20 is provided with a hollow tloor 24. An impervious bag or other waterproof means may be provided within the hollow HCC oor 24 so that a supply of water may be disposed therein. The water may be removed from within the hollow floor 24 by means of a manual pump 26. The pump 26 is supported on the wall Aand is provided with an inlet end which extends into the enclosure delined by the hollow oor 24. A step 25 is provided in the doorway 22 because of the diierence in height between the hollow door 24 Iand :the tloorV 12 of the bombshelter 10.

A hollow waste receiving tank 28 is mounted between the walls 16 and 18. The tank 23 is or" sumcient size so that it extends between the doorway 22 and the wall 14. 'Ihe tank 28 is provided with a vent pipe 30 which is adapted to extend to a point above ground level. A pipe 32 extends through the wall 16. One end of the pipe 32 is in communication with the interior of the tank 28.

' The other end of the pipe 32 is removably connected to Ia toilet device 34.

As shown more clearly in FIGURE 2, the toilet device 34 includes a generally semi-spherical bowl 36 having a conduit 38 tangentially disposed wit-h respect to a bottom portion thereof. The conduit 38 is hollow and provides communication between the bowl 36 and the pipe 32.V

The bowl 36 is provided 'with 4a radially outwardly extending -ange 40 having a groove thereon for receiving a portion of an rO-ring 41.

The O-ring 41 is secured to a flange 44 on a generally semi-spherical cover 42. The flange l44 is provided with `a handle I46 which facilitates separating the cover 42 from the bowl 36. The cover 42 is pivotably secured to the flange 40 on the bowl 36 by means of a hinge 4S.

A bore 5G' extends through the cover 42 and a depending boss 52. The bore 50 is in alignment with the intersection of the conduit 3S Aand the bowl 36.V A hollow plunger tube 54 is reciprocably disposed within the bore Si). The upper end of the tube 54 projects beyond the periphery of the cover 42 and terminates in a ared portion 56 simulating a funnel. The upper end of the bore the tube 54 is selectively closed by means Yof a screw or cork stopper 55 so as to prevent vapors from passing therethrough.

The lower end of the tube 54 extends to -a point adjacent the bottom of the bowl 36. The lower end of the tube 54 is provided w-ith a -threaded reduced diameter portion which extends through a central aperture in a dish shaped llexible member 58. The member 58 is retained on the tube 54 by means of a removable lock nut 60. In the lowermost position of the tube 54, the periphery of the member '58 engages the inner peripheral surface of the bowl 36. The member 58 is preferably made from a non-corrosive 4ilexible material such as rubber, polyethylene, etc. The member S8 is suiciently flexible so that the nut 60 may approach the bottom of the bowl 36 with the periphery of the member 58 being deformed and in eng-agement with the inner peripheral surface of the bowl 36.

The present invention is utilized as follows:

When -it is necessary to use the bombshelter 10, access may be gained by the passageway between walls 18 and 20 and the doorway 22. When the toilet device 34 is not in use, the respective elements thereof will be in the position illustrated in FIGURES 1 and 2. When it is desired to make use of the toilet device 34, the cover 42 may be pivoted in -a counter clockwise direction in FIG- URE 2 by applying pressure on the handle 46. The hinge 48 enables the cover `42 to rotate through au arc of approximately Liquid excrement introduced into the bowl 36 readily flows through the conduit 38 into the tank 28. Before -solid excrement is introduced into the bowl 36, the inner peripheral surface of the bowl 36 is preferably wetted by pouring -a small amount of water thereon.

The solid excrement may be caused to move from the Patented June 1l, 1963` bowl 36 through the conduit 3S and the inner peripheral surface orf the bowl 36 may be cleaned by manipulation of the plunger tube 54. The cover 4Z is lirst moved to the solid line position illustrated in FIGURE 2. Thereafter, the cork stopper 55' is removed andliquid may be poured through the tube 54. At approximately the same time, the tube 54 may be reciprocated so that the member 5S is deformed by engagement with the 'inner peripheral'surface of the bowl 36 thereby cleaning said surface. The cleaning of the inner peripheral surface'of the bowl 36 is facilitated by the flow of water or other liquid introduced into the bowl 36 by way of the hollow tube 54. lf water is utilized to ush the bowl 36, said water may be obtained from the hollow iioor 24 by means of the pump 26. The water may be conveyed from the pump 26 :to the bowl 36 in any convenient container.

The AO-ring 41 provides a gas tight seal between the cover 42 'and the bowl 36. The cork stopper 55y will be applied in the bore of the tube 54 thereby preventing escape of noxious vapors into the bombshelter 10.' The tank 28 may be provided with -a vent pipe 30 so that noxious vapors may escape to the 'atmosphere and prevent gases from building up the pressure Within the tank 28. Thev tank 28 may contain chemicals of the typeV generally utilized in septictanks and the like. If desired, the tank 28 may be provided with an overflow pipe which is con-Y nected to -a sewer,'a leeching eld, etc.

The tank 28 need not be in the bombshelter 10, but

may be adjacent an outside wall thereof or integral with an outside wall of the bombshelter. lt is within the scope of the present inventionfto mount the toilet device on the -tank 28 so that they may be installed as a unit. If de'- sired, the upper end 'of the plunger tube 54 may be provided with a container kof a ushing liquid which is dispensed each time :the tube 54 is reciprocated upwardly. Such dispensing may be accomplished by means of a check valve. Alternatively, the upper end of tube 54 may be threaded so that one end of a hose may be connested thereto with the other end of Vthe hose being connected to a source of liquid under pressure.

When the tank 28 is located as illustrated,v itsupperV surface may be utilized as a bench or `supporting surface.

vfor la variety of purposes. When the toilet device is connected directly to the tank, it should be removably secured thereto Ior disposed in well in the top Wallof tank 28 so that the top Wall may still be utilized as a supporting surface.

Thus, it will be `seen that I have provided a novel toilet device which does not require a supply of water to be connected thereto for ilushing the same. While the toilet device 34 has been illustrated in a bombshelter 1G, it will be appreciated that the same may be utilized on boats, in cottages, camps, etc.
